MAX3095CSE+T - 10Mbps Quad RS-422/RS-485 Receiver | Analog Devices
部品番号: MAX3095CSE+T ✓ 生産中MAX3095CSE+T 概要
An RS-422/RS-485 receiver is a differential line receiver within the broader interface IC and data-converter hierarchy. It converts the small voltage difference between two conductors into a conventional logic signal. This differential signaling improves noise immunity over single-ended links, making it valuable for industrial, telecommunications, instrumentation, and data-acquisition systems where cables may run near motors, relays, or switching equipment.
The MAX3095 integrates four receivers into one package. Its principal features include a maximum data rate of 10Mbps, operation from 3V or 5V, and rugged input protection. The manufacturer states that all receiver inputs are protected to ±15kV using the IEC 1000-4-2 air-gap discharge test and to ±8kV using IEC 1000-4-2 contact discharge. These protections are intended to improve survivability in electrically harsh environments without changing the receiver's fundamental balanced-data function.
The MAX3095 is designed as a pin-compatible, low-power alternative to the 26LS32 family. Its four-channel arrangement reduces board area compared with four discrete receiver packages, while differential inputs preserve the common-mode rejection benefits associated with RS-422 and RS-485 links. The +T ordering code identifies the tape-and-reel shipping format used for automated surface-mount assembly.
Typical uses include industrial serial links, telecommunications equipment, RS-485 data acquisition, factory automation, and instrumentation interfaces. Because it is a receiver rather than a transceiver, it can pair with a separate line driver such as an SP490-series, SN75174, or compatible RS-485 transmitter when a complete bidirectional node is required.
Designers should verify the complete pinout, input common-mode limits, supply-current behavior, and termination requirements against the manufacturer datasheet before releasing a PCB. Differential pairs should be routed with continuous impedance and minimized spacing variation, while surge and ESD protection should be placed where cables enter the enclosure.
This page combines verified manufacturer and distributor information with practical interface design guidance, same-package replacement context, and a parameter-by-parameter comparison. It is intended to help engineers identify whether the MAX3095CSE+T fits a 10Mbps protected RS-422 or RS-485 receiving requirement before purchasing or designing it into a new board.

Industrial RS-485 Data Acquisition
The MAX3095CSE+T fits industrial data-acquisition nodes that receive differential signals from remote sensors over RS-485 links. Its four receivers permit multiple channels to share one 16-pin SOIC package, while the 10Mbps maximum data rate supports communication well beyond typical low-speed field-bus traffic. The ±15kV IEC 1000-4-2 air-gap input rating adds valuable protection when cables pass near industrial relays, motors, or switching nodes. Because the MAX3095 is receive-only, an SP490 or SN75174-family transmitter can provide the corresponding drive function where a bidirectional node is required. Final design work must verify common-mode limits, fail-safe behavior, termination values, and the complete pin assignment.
おすすめ
Factory Automation Control Interfaces
The MAX3095CSE+T is suitable for factory automation equipment that receives commands or measurements from differential field-bus wiring. A 10Mbps receiver capability provides margin for deterministic control and diagnostic links, while four integrated channels simplify multi-axis, multi-sensor, or redundant-interface designs. Its protected receiver inputs are particularly relevant in cabinets containing relays, contactors, motor drives, and long cables that can introduce electrostatic discharge. Engineers should route the differential pair as a controlled-impedance pair, maintain the receiver ground reference correctly, and confirm that the selected transmitter and cable topology remain compatible with the MAX3095's specified common-mode and fail-safe behavior before production release.
おすすめ
Telecommunications Equipment
The MAX3095CSE+T addresses receive-side requirements in telecommunications equipment carrying balanced RS-422 or RS-485 signals. Its low-power, four-channel architecture can reduce the number of receiver packages in line cards, monitoring modules, and test equipment. The verified 10Mbps capability supports high-rate signaling, while all-input ESD protection helps improve robustness in environments where exposed cables and grounded metal structures can create transient discharge events. The IC should be paired with a compatible line driver, and designers must provide appropriate cable termination rather than assuming that receiver protection eliminates the need for system-level surge protection. Supply decoupling, ground-current planning, and logic-level compatibility with the surrounding controller remain essential layout considerations.
おすすめ
Instrumentation and Test Equipment
The MAX3095CSE+T can serve as the protected receive front end in instrumentation and automated test equipment that accepts differential measurements or control commands. Four channels in one 16-pin SOIC package leave more board area for analog front ends, signal conditioning, and isolation circuitry. The 10Mbps data-rate rating supports laboratory and production-test communication, while ±15kV air-gap and ±8kV contact ESD ratings provide a useful layer of input protection. For precision measurements, engineers should still account for receiver offset, noise, propagation delay, and system grounding because those values were not included in the supplied verified data. The complete manufacturer datasheet should be consulted for timing, input thresholds, output behavior, and recommended application circuits.
おすすめ
RS-422 Level Translation
The MAX3095CSE+T can receive differential RS-422 signals and present them to a compatible controller or transceiver in systems that require a protected receive-only function. Its four channels make it practical to consolidate several balanced links without using separate single-channel packages. The 10Mbps maximum rate also allows the device to be considered for faster data links when the source, cable, and logic interface support the same rate. Differential reception preserves noise rejection over long or unbalanced environments, but correct reference grounding and termination remain important. Engineers should compare the MAX3095's exact input thresholds and common-mode range with the transmitter output before using it as a generic logic-level translator.
おすすめ
Building and Environmental Controllers
The MAX3095CSE+T can be used in building-control equipment that receives commands from differential bus wiring distributed throughout a facility. Its four-channel SOIC package supports compact multi-point interfaces, and the protected inputs suit installations where long cables connect controllers to remote sensors or actuators. The 10Mbps capability provides ample bandwidth for control and status traffic, although real networks normally operate below that limit to preserve signal integrity. A separate compatible transmitter is required for nodes that must send data. Designers should use twisted-pair wiring, avoid routing communications paths parallel to high-current power conductors, verify surge protection at the cable entry, and confirm the receiver's common-mode limits against the selected network topology.

設計ノート
Route each RS-422 or RS-485 receiver input as a controlled-impedance differential pair with continuous reference to the device ground. Keep the two conductors together, minimize stubs, and avoid discontinuities that create reflections at the supported 10Mbps data rate. The supplied data does not specify the complete input thresholds or common-mode range, so these values must be obtained from the manufacturer datasheet before confirming signal compatibility.
Do not treat the ±15kV air-gap ESD rating as permission to omit system-level surge protection. Place appropriately rated protection at the cable entry when the interface can be connected to outdoor or untrusted wiring, and verify that the protection device does not disrupt the differential signal or ground reference. Also confirm that the selected bus topology, termination, and fail-safe behavior agree with the MAX3095 datasheet.
Place the receiver IC close to the connector or protection network and maintain a compact return path for the differential signals. Keep switching regulators, high-speed clocks, and relay-drive traces away from the receiver inputs. The MAX3095 combines four channels in one 16-pin SOIC, which can shorten protected traces and reduce board area, but channel-to-channel routing must still preserve symmetry and avoid shared high-current paths where practical.
